The Gateway Arch -- Unique Perspectives [CS2]

The National Park Service and WJE investigated the Gateway Arch, including the visible stains on the stainless steel skin, from 2005 to 2014. The team used a combination of traditional techniques such as field microscopy and high-powered spotter scopes and innovative technologies such as casting molds of the surface, helmet-mounted video cameras, and cloud-based real-time communication to facilitate the challenging investigation. This presentation will discuss development of the access program, the staining assessment, cleaning trials, and the overall conclusions of the investigation.
